if i take manually item from input slot the extraction module pulls the item,

got it in debugger not really sure what's wrong, lugs like it try route input item ? iron bar ?

It breaks loop and return.

adv extractor still got same issue, didn't notice thy not share tick implementation

Yeah I'm thinking that those slots are the same inventory handler, and whatever mod that is doesn't let LP pull out of the first slot, and instead of skipping it it just gives up

It’s gregtech ce

It break up @195

The inventory handler looks like got proper input and output inventories, why extractor would try export from input slot ? Or this is not always true for tile entities ?

gregtech item handler treats input and output as single inv ? and size return total size, slot 1 => first slot in iput handler. ..

not sure if proper fix, but it fixes my problem.
